WM. A. N. LONG, OF FISHERVILLE, NEW HAMPSHIRE, ASSIGNOR TO J. B. RAND,OF SAME PLACE.

ROCKING- CRADLE.

Specification of Letters Patent No. 33,045, dated August 13, 1861.

To all whom t may concern:

Be it known that I, WVM. A. N. LONG, of Fisherville, in the county ofMerrimack and State of New Hampshire, have invented certain new anduseful Improvements in Self- Rocking Cradles; and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the annexed drawings, and to the letters ofreference marked thereon, in which- Figure 1 represents a vertical crosssection of the machinery and Fig. 2 a longitudinal section of the wholemachine.

The nature of my invention consists in the employment and arrangement ofcertain devices the peculiarities of which will be hereinafter fully setforth.

To enable others skilled in the art to make and use my invention I willnow describe its construction and operation.

(A) represents the frame provided at one end with a box for themachinery as shown in Fig. 1.

(B) is the cradle which is hung on pivots (c c). It should beparticularly observed that the bottom of the cradle is composed of twopieces of equal width both-of which in oline toward the center at asuiicient angle to prevent the infant from rolling from side to side,thus enhancing the comfort of the child, besides making the cradleoperate more perfectly. One end of the cradle should be provided withpins which will regulate its swing.

(C) represents the large ratchet wheel and (d) the small one, both uponthe same shaft as fully seen in Fig'. 1.

(a) is a pawl which is pivotepd to the (g) represents a spring placedbehind the pawl.

(f) is a shaft upon which is secured the sleeve (7L). To this sleeve ispivoted the escapements (Z) o) in the manner shown in Fig. 1. Y

(e e) are pins secured to the escapements and are stops. Thus it willibe seen that the working of the escapements o) will be regulated bymeans of pins (e e) and stops (7c) represents a rod which is secured tothe shaft (f), between the box and cradle as fully shown. At the lowerend of this rod is attached a short lever (p), which lever is providedat its end, with a small hole, for the purpose of slipping over a pin inthe end of the cradle.

(G) represents a spiral spring, and is secured as seen in Fig. 2.

(m) is a cord, one end of which is attached to spring (G) while theopposite end, passing under pulley (o), is secured to the same shaft,upon which the two ratchet wheels and are located. It should be observedthat the end of said shaft is square, in order that it may be turned bya key.

The operation of my invention is as follows: It is first wound up bymeans of a key, which, when done the ratchet wheels immediately commenceto revolve. Now it will be noticed, that as the escapements o) aresecured one at the bottom and the other at the top of sleeve (71,),that. the ratchet wheel (C) as it revolves, will be caught alternatelyby the escapements, thus giving a swinging motion to the cradle andpreventing at the same time the ratchet wheels from revolving toorapidly.

)Vhcn the machine stops, all that is necessary to again put it inmotion, is to wind it up.

Having thus described my invention what I claim is- 1. The employment ofthe spiral spring (G) as and for the purpose set forth.

2. The employment of a cradle whose bottom shall be inclined when saidcradle shall be operated substantially as and for the purpose set forthand described.

VIn witness that I claim the foregoing I have hereunto set my hand inthe presence of witnesses VM. A. N. LONG.
